YARN CARRIER.

Application led April 18, 1928, Serial No. 270,968, and in GermanyFebruary 12, 1927.

rI`his invention relates to yarn carriers or frames such as are used indyeing textile fabrics for example, for suspending the yarn hanks in thedyeing or washing machine. In such machines with reversibly circulatingdye liquor, the liquor tends to drive the suspended yarn hanks upwardswhen circulating in anupward direction. -Under these circumstances thehanks would float on the surface of the liquor and would rise partly outof the liquor if steps were not taken to hold the hanks down below thesurface. For this purpose vit is customary to insert sticks or bars inthe lower ends of the loops of the yarn hanks or else a lattice gratingis placed at some distance above the yarn bars, which only permits theamount of lifting of the hanks from the place on which they rest that isre'- quired for uniform dyeing. These appliances hamper the freemanipulation which is desirable for the transposition and the arrangingof the bars and hanks. Efforts have been made to counteract thisdifliculty by coiling the yarn hanks tightly on the bars. This howevergives rise to stratiications of varying density or thickness.

According to the present invention two yarn carrier bars situated at adistance apart from each other are employed, which are releasablyconnected with one another, and which can be freely manipulated togetherby the dyer like a simple yarn bar. The lower of these connected yarnbars serves for the suspension of the hanks and the upper for limitingthe movement of the yarn beneath the surface of the dye liquor when thedirection of movement of the liquor changes. The bars are made from asubstance which cannot be forced upwards by the circulating liquid, suchas, for instance, of metal unaffected by the liquid.

Various constructional forms of the invention are illustrated by way ofexample in the accompanying drawings, wherein Fig. l shows inlongitudinal sectional elevation a dye vat with a number of suspendedyarn carriers according to my invention,

Fig. 2 shows a cross section on the line 2-2 in Fig. 1,

Fig. 3 shows on an enlarged scale, partly in section, one end of a yarncarrier according to Figs. l and 2, and

Fig. 4 is a cross section on the line 4-4 in Fig. 3.

Fig. 5 shows in cross section the upper part of a dyeing or washing vatwith another yarn carrier according to my invention, and

Fig. 6 is a partial section on the line 6-6 in Fig. 5.

As Figures l andQ show, the yarn hanks l are suspended in a vatQ, inwhich, by means of a partition 3, 4, compartments are divided off whichcommunicate with one another. In these compartments the washing ordyeing liquor which fills the vat nearly up to its upper rim 5 is movedby a suitable pumping mechanism or the like in constant circulation, thedirection of which is reversed from time to time.` Such vats are known.

The new yarn carrier consists of two parts 6 and 7 releasably connectedwith one another. t hangs down with its central part, the yarn bar 6,which receives the yarn hanks, between its supporting ends 8 and 9, insuch a way that when the yarn carrier is placed upon the edges 5 of thevat, the yarn bar 6 is immersed in the liquor. The second bar, whichforms the holding down ledge 7, is releasably supported in the yarncarrier 6 at a distance from the bar. For this purpose the supportingends 8 and 9 of the yarn carrier are provided in the upright parts 10with slot-like recesses 11 and 12, which are open at the top, asv shownin Figs. 1 to 4, and into which the bar can be inserted from above. Itis a particular advantage of this method of supporting that theholding-down bar 7 can be inserted after the yarn carriers are suspendedin the vat 2 and can be taken out before the yarn carriers areremoved.It therefore does not hinder the transposition and arranging of the hankcarriers or of the hanks 1, the bar or ledge 7 which is situated at adistance above the yarn carrier 6 does not prevent the hank from beinglifted fromthe carrier bythe dye liquor but it is situated so far belowthe liquid surface that it keeps the yarn hanks 1, which the liquidtends to drive upwardly when circulating below the surface of theliquid. l

In the second constructional form, illustrated in Figs. 5 and 6, theyarn carriers consist of simple straight bars or tubes 6, which arelocated underneath the surface of the liquor on steps or shoulders 18 inthe vat 2. Over these straight yarn carriers the .yarn hanks 1 can beslipped more easily than over the yarn carriers 6, shown in Figs. 1 to4, which are joggled at both ends. The holding-down bar or ledge 7 ishere provided at llO both ends With clamps or paWls 14, Which, When theledge carriers 15 are put on,-a=,t first yieldfto the carrying bar 6 andsubsequently swing back and engage underneath the latter, as shown inFig. 6. In this Waythe connection between the two bars 6 and 7 isestablished. Each carrier bar 6, hanging in the Y paWls 14 of itsholding-down ledge 7, can be lifted out With this ledge and transposed,Without leaving the liquor, since the yarn bar located entirelyunderneath the surface of the liquor can be taken hold of by the handles15. In this construction also the holdingdown ledges 7 can be mountedindividually even after the introduction of the yarn carriers 6 into theliquor.

Vilhat I claim is 1. A yarn carrier, more particularly for hank yarndyeing and Washing machines, comprising a carrying member, a holdingdown member situated at a distance above and releasably connected Withsaid carrying member, said carrying member and said hold- `like a simpleyarn bar.

2. A yarn carrier, more particularly for hank yarn dyeing and Washingmachines, l

comprising a carrying bar adapted to have -hanks of yarn suspendedtherefrom, a holding down bar adapted to be releasably connected Withsaid carrying bar, releasable paWls carried by said holding down bar,said pawls being' adapted, when the holding down bar is mounted upon thecarrying bar, to hook firmly under said carrying bar, said carrying barand said holding down bar co-operating With one another to holdthesuspended yarn hanls underneath the surface of the liquor and beingfreely movable together by the dyer like a simple yarn bar.

In testimony whereof I have signed my name to this specification.
